Viscoelastic properties of lower extremity muscles after elite track cycling sprint events: a case report

open access: yesCentral European Journal of Sport Sciences and Medicine, 2020
Sprint cycling events require a high level of anaerobic capacity and therefore may affect peripheral fatigue throughout exercise-induced muscle damage. In fact, those alterations might decrease power generation. This study was performed on a 23 years old

The relationship between cycle track width and the lateral position of cyclists, and implications for the required cycle track width

open access: yesJournal of Safety Research, 2023
Sufficient cycle track width is important to prevent single-bicycle crashes and collisions between cyclists. The assumptions on which the minimum width is based in guidelines is founded on only a few studies. The aim of the present study is to investigate the relationship between cycle track width and lateral position of cyclists.We conducted an ...

Identification of key parameter influence on efficiency of chain drive for track cycling − Preliminary results

open access: yesMechanics & Industry
The presented paper investigates the efficiency of chain drive transmissions in track cycling, where performance optimization is critical as a win or loss between athletes is often decided in a matter of 1/100 seconds.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Cycling and the city: a case study of how gendered, ethnic and class identities can shape healthy transport choices. [PDF]

open access: yes, 2011
As a form of 'active transport', cycling has been encouraged as a route to improving population health. However, in many high-income countries, despite being widely seen as a 'healthy' choice, few people do cycle for transport.

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.
